| Abstract: | Plastics enter in terrestrial natural system primarily by agricultural purposes, while acid rain is the result of
anthropogenic activities. The synergistic effects of microplastics and acid rain on plant growth are not known. In
this study, different sizes of polyethylene terephthalate (PET) and acid rain are tested on Lepidium sativum, in two
separate experimental sets. In the first one we treated plants only with PET, in the second one we used PET and
acid rain together. In both experimentations we analyzed: i) plant biometrical parameters (shoot height, leaf
number, percentage inhibition of seed germination, fresh biomass), and ii) oxidative stress responses (hydrogen
peroxide; ascorbic acid and glutathione). Results carried out from our experiments highlighted that different
sizes of polyethylene terephthalate are able to affect plant growth and physiological responses, with or without
acid rain supplied during acute toxicity (6 days).
Short description: This study showed that different sizes of PET microplastics affect physiological and biometrical
responses of Lepidum sativum seedlings, with or without acid rain; roots and leaves responded differently |
